someone mentioned an issue with small spacers not fitting. true, they weren't. However, this is an easily fixed issue with some glue on the bits to keep them in place. and we noticed that the tabs were a bit hesitant to open after snapping. we only remember where we use them. although that hasn't been a problem so far. So I am sure that in this case we will find a way to tweak them so that they still work. because the case itself appears to be made of fairly durable plastic.
